Technical details
Organic coated steels are synonymous with a wide range of colours associated with an endless possibility of surface patterns such as smooth, grained, embossed, textured, or orange peel effect. In addition, several finishes can be achieved: from matt to high gloss and even metallic finishes.
In construction, organic coated steels that are applied on metallic substrates Z or ZM are mostly based on:
• Saturated Polyester (SP)
• Polyurethanes (PUR)
• Polyvinyl Fluoride (PVDF)
Layer thicknesses for external applications range from 25 to 75µm.
Our range of organic coated steels for outdoor applications includes:
• Granite® 25 to 75µm thick paint coating systems with excellent durability performance, corrosion resistance of up to RC5+*, and UV resistance of up to RUV5*
Our range for indoor applications includes:
• Estetic® up to 25µm thick paint coating systems
* According to the EN 10169-2021 standard

Industry newsBuild durable solar roofs with Granite® organic coated steels
16 November 2022With the demand for electricity growing rapidly, solar energy production via photovoltaic (PV) modules installed on roofs is becoming a solution of choice for developers.Prepainted steel roofing solutions are light, durable, and made from eco-friendly materials. They are also able to sustain the loads required for PV module installation. It's no wonder that installing solar PV systems on steel roofs is increasingly common.However, some precautions should be taken with PV modules, such as ensuring enough space between the module and the organic coated steel surface to enable water drainage and ventilation. With this condition fulfilled, prepainted steels are the preferred material for roofs with PV modules - whatever the type of building.

Impressive aesthetics for buildings
As the European leader for organic coated steels (also known as prepainted steels), ArcelorMittal Europe - Flat Products offers a unique range of products for each application, building, environment, performance requirement, and aesthetic demand.
Moreover, we are continuously reducing the environmental impact of our steels.
For outdoor applications, our Granite® range offers a solution for each component of a building envelope:
• Granite® HDXtreme: the latest prepainted steel in the organic coated range and the most durable organic coating for construction
• Granite® HDX: where outstanding resistance to corrosion and colour stability are required
• Granite® Silky Shine: synonymous with elegant finishes for facades
• Granite® Quartz and Granite® Storm: for extended durability of your roofing applications combined with exceptional aesthetics
• Granite® Impression: with Granite® Impression Cloudy, Wood, Agate, and Patina
• Granite® HFX Cool: for standing seam roofs and facades
• Granite® Ultramat: specifically for roofing tiles – with a high quality and flexible paint system
For indoor applications, we recommend our Estetic® range:
• Estetic® BioAir Mat: made of a 100% biobased resin which improves indoor air quality
• Estetic® Clean: meets the most stringent requirements for cold rooms
• Estetic® Mat: with a light matt finish with excellent resistance to marking
• Estetic® Tex: with a grained anti-scratch finish for robust usage
The benefits of ArcelorMittal organic coated steels are numerous for construction stakeholders:
• Long-term aesthetics and durability of colours: a defined minimum paint thickness is compulsory to ensure the beauty and durability of a building.
• Robust and resistant against harsh environment conditions: the thickness of the metallic coating layer is optimised to protect the steel substrate.
• Creative design for complex forms: flexibility and adhesion of the paint are key to allow for smooth processing operations.
• Sustainability: the steel used is manufactured in a safe and environmentally responsible way and free of heavy metals or substances of very high concern (REACH).
